Like most people, my first encounter with the word “Monopoly” was through the board game by that name. It would be years before I studied the workings of a market controlled by a monopoly, but as a child I loved to become part of intense games of Monopoly, acquiring as many houses and hotels as I could with the money I had and earned from my investments. I thought of those little houses that dotted the spaces on the board game when I took my daughter and her friend to play in a very special park recently.

I find it interesting when economics is applied to offbeat topics.This is done in the best seller “Freakonomics,” which looks at a variety of social issues using the tools of economics. My own research applies the discipline of economics to studying altruism and nonprofit organizations, topics that are probably not the first things that come to mind when one thinks of economics. I also recall the professor who taught me macroeconomics many years ago, whose own research was on “envy”. I found myself thinking of him recently as I ran into one of my daughter’s former teachers as we stopped by the library on the way home from her summer camp. With wet hair and a bathing suit under her shorts, the teacher said that she looked like she was having fun. I could only add “I want her life.”

There is a function in math called the “Greatest Integer Function,” which assigns a value to every number that is the largest integer less than or equal to that number. For example, the numbers 1, 1.2 and 1.9 would all have a value of 1 for this function. As you can imagine, this leads to a graph that looks a lot like a set of stairs, and is the typical example used when describing what a “discontinuous” function looks like. I found myself thinking of this over the past week, as I watched my daughter move up a grade in school.

As I age, my eyes are staring to betray me. This is something that I particularly notice when I am reading things that involve superscripts or subscripts, which occurs often in math and economics.

An important topic from Algebra is that of intersecting lines. Equations can be written representing lines on graph paper, and Algebra, especially Linear Algebra, helps find points that are contained on more than one line, where two or more lines intersect. I thought of this last weekend as I watched former students walk across a stage to receive their diplomas, and realized that their lives had intersected with mine. I know that my life is richer for having known them.

One of the concepts I teach in my Quantitative Reasoning class is the idea of “Exponential Growth.” Such growth, where a variable grows by a fixed percent, is found in such things as population growth and the growth of money earning interest. I found myself thinking of this recently as I watch my daughter grow at a rate that seems to be exponential, outgrowing clothes almost before they can be worn and threatening to soon pass me by in terms of height. I am thrilled to see her turning into a healthy young lady, but I have to pause as I realize that, as she grows, she is exposed to aspects of life that I would prefer to shield her from.

Central to the subject of Economics is the idea of “utility maximization.” This concept proposes that people choose the optimal assortment of work, goods and leisure given the constraints they face. As calculus is applied to compute such choices, it is assumed that the economic agent is strictly self-interested, an assumption I find myself thinking about as we celebrate Mother’s Day this weekend.

In economics, we talk about purchasing machinery that is used in producing a product as “investment”  in capital, and in acquiring skills and experience that will help an employee perform a job more efficiently as “human capital investment.” It is this later type of investment that seems to be on the forefront of the minds of many of my fellow parents who I run into lately.

One of the topics I teach in my Quantitative Reasoning class is the calculation of a retirement savings goal. It is always shocking to my students how much money they will need to save in order to live comfortably in their retirement. However, as daunting as the goal may seem, I emphasize that it is important to begin to put some of what we earn away into a safe fund so we can draw on it in the future, when we need it. I found myself thinking of this concept recently when I attended a track meet in which my daughter and her young friends competed. I had to laugh when she asked me after her meet "did you like to run when you were a kid, too, mom?"

When people learn that I am both a full professor of Mathematics and an Economist who studies the economics of nonprofit organizations, they are often confused. “What do you teach?” is the common question that follows, to which there is a quick answer, a short answer and a long answer.
